01·Course Characteristics
A legendary European Championship course that demands ultimate discipline. Deceptive rolling hills in the Taunus region and baking afternoon heat along the Main River will test your pacing and thermal management to their absolute limits.

02·Course by Section
A calm, clear forest lake swim south of central Frankfurt. It features a rolling-start format and a brief sandy run across the beach for the Australian exit before diving in for loop two.
After departing T1, head north to Frankfurt and complete two rolling loops through the Taunus hills. The signature test is 'Der Hammer' in Bad Vilbel, a short but brutally steep 20% climb lined with spectators.
A flat and lightning-fast four-loop out-and-back course along both banks of the Main River, crossing major bridges twice per lap. High spectator density provides immense energy, but the asphalt has zero shade.

Expect a cool 14-16°C start at the lake, but prepare for 28-32°C during the run. Actively utilize every single aid station for ice and wet sponges to lower your core temperature before heat exhaustion sets in.
Front-load your nutrition on the bike when digestion is easiest, targeting 80-100g of carbohydrates per hour. Due to high afternoon heat, execute an aggressive hydration and high-sodium replacement strategy on the bike and run.
Protect your legs on the rolling bike course by riding conservatively and capping your effort on the 20% Heartbreak Hill. An aggressive bike leg on these rhythm-changing hills will guarantee a massive fade during the marathon.
This is a split-transition race. You must check your bike in at T1 (the lake) the day before the race, and utilize the official race shuttles from downtown Frankfurt to the swim start on race morning.
The swim takes place in Langener Waldsee, where water temperatures typically range between 18°C and 22°C (64.4°F to 71.6°F). This means the swim is usually wetsuit-legal for age-group athletes, though it can occasionally be borderline if the lake warms up. You should prepare for both wetsuit and non-wetsuit scenarios just in case.
The 180 km bike course is moderately challenging, featuring between 1,600 and 1,800 meters (5,249 to 5,905 feet) of total elevation gain through the Taunus region. While the asphalt is smooth and fast, the rolling hills and the steep 20% gradient of 'Der Hammer' (Heartbreak Hill) require a highly disciplined pacing strategy. It is more demanding than flat courses like Hamburg, but less extreme than mountain races like Lanzarote.
Because this is a split-transition race, T1 is located 20 km south of the city at Langener Waldsee, while T2 and the finish line are situated in downtown Frankfurt. You must check your bike into T1 at the lake on the day before the race. On race morning, it is highly recommended to take the official event shuttles from central Frankfurt directly to the swim start.
The marathon consists of four flat, fast loops along the banks of the Main River, totaling only about 95 meters (312 feet) of elevation gain. However, the paved course has virtually no shade, exposing you to high afternoon temperatures that often reach 28°C to 32°C (82°F to 90°F). To manage this intense heat, you must aggressively use the aid stations for ice and wet sponges while keeping up with your hydration.
With afternoon temperatures frequently exceeding 30°C (86°F), you should target a high carbohydrate intake of 80 to 100 grams per hour early on the bike when digestion is easiest. Combine this with aggressive sodium and fluid replacement to counteract heavy sweating. Once on the run, transition to easily digestible simple sugars like gels and sports drinks to prevent heat-induced gastrointestinal distress.
